I would respect Canadian Blood Services more if it took a stronger position on gay blood donations. Either stick with the lifelong ban and admit that it's a super-cautious approach to try to mitigate against potential infections we don't yet understand, based on the deadly mistakes made in the past with HIV. Or focus on the bloodborne diseases we do know about, and adjust the ban accordingly to six-months or one-year, as would be consistent with the current science of detection. Either one of these approaches would be a more defensible posture than the arbitrary five-year ban Canadian Blood Services has chosen to champion.
